Design for Machining: Prototyping Guidelines
A DfM-first approach prioritizes tool access, rigid features, and tolerances that match test needs.
Automatic DfM checks at upload identifies tool access, wall thickness, and other risks so you can adjust the 3D model before production. UYEE helps match multi-axis selection to the geometry instead of forcing a 3-axis setup to approximate a 5-axis method.
Geometry, tool access, and feature sizing for 3–5 axis
Keep walls appropriately thick and long enough features within the cutter reach. Minimum wall thickness varies by material, but designing broader webs cuts chatter and tool deflection.
Use generous fillets at internal corners to allow proper cutter engagement. Deep, small pockets should be designed with ramped entries or multiple setups in mind.
Tolerance planning for appearance vs functional parts
Separate cosmetic and functional tolerances early. Tight form tolerances belong on critical interfaces. Looser cosmetic limits cut cost and reduce cost.
Define datum schemes and tolerance stacks for assemblies and kinematic mechanisms. Document measurement plans for critical features so acceptance criteria are clear before the first run.
- Set minimum wall thickness, feature depths, and fillets to improve tool access and stability.
- Use 5-axis when feature relationships or undercuts need single-setup accuracy; choose simpler fixtures when speed matters.
- Specify best practices for threads, countersinks, and small holes to limit deflection and ensure repeatable quality.
- Early DfM reviews cut redesign and speed prototyping iterations.
| Focus | Design Rule | Benefit |
|---|---|---|
| Wall & Fillet | Wider webs, radiused corners | Reduced deflection, better surface finish |
| Setups | Prefer 5-axis for complex relations | Fewer fixtures, preserved geometry |
| Tolerances | Functional vs cosmetic | Cost control, faster cycles |

| Quality & docs | FAI, CoC, inspection reports | Regulated tests, production handoff |
| Flexibility | Fast reorders, design revisions | Iteration-driven development |
CNC vs Injection Molding and 3D Printing for Prototypes
Choosing the right fabrication route can reduce time and cost when you move from concept to test parts.
Low quantities force a practical decision: avoid long waits or invest in tooling for lower unit cost. For many low-quantity runs, machined parts beat molds on schedule and upfront cost. Printing is fastest for concept visuals and complex internal lattices, but may not match mechanical performance.
Cost, time, and fidelity trade-offs at low quantities
Injection molding demands tooling that can take many weeks and significant budget in cost. That makes it hard to justify for small lots.
Machined parts avoid tooling fees and often provide tighter dimensional control and stronger material behavior than many printed parts. Chips from metal removal are recyclable to reduce waste.
- Time: printing for hours to days; machining for days; injection may take weeks to months.
- Cost: low unit counts favor machining or printing; molding only pays off at volume.
- Fidelity: machining delivers consistent tolerances and surface finish; printing can show layer anisotropy and layer artifacts.
When to bridge from CNC prototypes to molding
Plan a bridge to injection when the design is stable, tolerances are locked, and material choice is locked. Use machined parts to prove fit, function, and assembly before committing to a mold.
Early DfM learnings from machined runs reduce mold changes and increase first-off success. Right-size raw stock, optimize nesting, and recycle chips to improve sustainability during the transition.
| Attribute | Best for | Notes |
|---|---|---|
| Printing | Ultra-fast concepts, complex lattices | Low strength; good for visual and some functional tests |
| Machining | Small lots, tight tolerances, mechanical tests | Avoids tooling; recyclability reduces waste |
| Injection | High-volume production | High upfront tooling; lowest unit cost at scale |

3D printing and SLA
SLA printing delivers smooth surfaces and fine detail for concept models and complex internal geometries. It supports speedy visual checks and fit trials before moving to harder materials.
Rapid injection molding
Rapid tooling, family molds, and multi-cavity options let teams bridge to higher volumes once designs stabilize. Overmolding can add soft-touch or bonded layers in the same run.
Multi-process programs often mix CNC parts with printed components or sheet metal to accelerate subsystem integration. Material and process selection focus on validation goals, schedule, and budget.
- Sheet metal: fast iterations for formed parts and brackets.
- SLA printing: high-accuracy surfaces and internal detail.
- Rapid molding: cost-effective bridge when volumes justify tooling.
